ANTISKIIDDING DEVICE FOR VEHICLE-TIRES.

Specification of Letters Patent.

Patented Oct. or, 1916.

Application filed February 28, 1916. Serial No. 80,776.

-. LEWIS D. SNOVER, citizens of the United States, residing at \Yaterford, county of Oakland, State of Michigan, have invented a certain new and useful Improvement in Antiskidding Devices for Vehicle-Tires, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being bad to the accompanying drawings,-which form a part of this specification.

Our invention has for its object adevice which may be readily attached to or removed from the wheel of a vehicle, and which consists essentially of an outer shoe conforming to the contour of a tire having calks projectin from its tread adapted to prevent skiddlng by affording greater traction.

Another object is to provide removable calks, in order that they may be replaced when worn; thus prolonging the life of the device.

Another feature of the invention consists in arranging the calks so as to project at an angle to the trend of the tire and toward the sides of the wheel, thereby oii'ering greater resistance to side or lateral slippage.

Another object of the invention is to eliminate the wear upon the tire common to devices of this character, the construction being such that it is not only adapted to insure the wheel against skidding, but may serve as .a shoe to protect the tire or casing when vice secured thereto, with a portion broken away and in section to more clearly disclose construction. Fig. 2 is a perspective view of the device, and indicating a fragment of the holding straps connected therewith.

Referring now to the letters of reference placed upon the drawings :-A, denotes the outer casing of a pneumatic tire; B, a supporting rim.

(1, indicates the folly of a wheel.

D, is a shoe formed of leather, rubber, or

other suitable material overlapping the sides and tread of the tire.

E, denotes transverse metallic straps riveted at e, to the shoe and substantially conilj orrmng to the cross sectional contour of the ire. F, F, indicate metallic strips or links, also rivetedto the shoe and provided with eyes i, to receive the ends of the metallic straps E, with which they articulate.

G, G, denote flexible straps engaging the looped ends f, of the strips F.

G, is a suitable buckle carried by the respective straps to receive and engage the end of the straps overlapping the wheel folly, whereby the device is secured in position.

-Having indicated the several parts of the device by reference letters, its construction and operation will be readily understood.

The shoe E, which may be made of leather, rubber, or other suitable fabric, is shaped to conform to the cross sectional contour of the tire. and may be used to cover a blow-out or other rupture of the tire when necessary, anl when used for this purpose, the calks m y be removed if desired.

It will be observed that the removable calks are preferably positioned quite near lapping the tire laterally. Upon the. calks becoming worn through use, they may be removed to be replaced by new calks, or the calks may be removed and the shoe used without, if the condition of the road is such as to make their use unnecessary.

Having thus described our invention, what we claim is v A device adaptable to a wheel-tire, including a shoe conforming to the periphery there-sf, and hm mg a ry-law; tz ansversely thereon metallic straps, smdmetalhc straps,

having articulated; thgn'aQq metallib'jlinks, said links beingflrivetd'fit-fifiheir'mid lengbhs,
